This thermally broken awning window is not like the rest. Our awning window outperforms most with high impact and non-impact certifications. This window is similar to a casement style, but has a smooth operating lever on the side of the frame that controls the window in an open and closed position from the bottom out. Great for basements or matching up with the WinDoor 9060 Casement model. Ridged construction and outstanding Energy Star performance you cannot believe.
